A sinus infection is the inflammation of the paranasal sinuses (mucosal lining) due to colonization of a pathogen. It is usually bacterial in origin (acute bacterial sinusitis) but other pathogens may be involved.
In cases where these sinus cavities get inflamed, the mucus and pus start collecting inside of them. When the holes that connect these sinus cavities to the nose become plugged, then the sinus cavities won’t normally drain leading to a sinus infection. These infections can be either acute or chronic.
The mucus and pus accumulation will lead to a sensation of fullness and heaviness in the face, pain and pressure in the face, headache, etc. Continue reading about the 10 most common sinus infection symptoms.
Symptom #1: Face Pain and Pressure
Because of the accumulation of the mucus and pus inside the sinus cavities and because of the clogged sinus drainage pathways to the nasal cavity, pain and pressure in the face around the affected sinus cavity are common. The congestion pressure on the nerves of the face occurs.
This pressure feels usually like a dull and throbbing pain located behind the nasal bones, cheeks, eyes or forehead where the sinus cavities are located. The pain and pressure on the face tends to get worse in cases when a person leans the head forward or when the face is touched.
